Abstract
There is provided an inexpensive electromagnetic shield that can achieve exceptional shielding and display visibility characteristics, and provide high environmental resistance as necessary. In an electromagnetic shield (), an intermediate layer () is formed on a glass substrate () comprising soda lime glass, an electroconductive layer () of Al is formed thereon, and openings () are formed by wet etching on the intermediate layer () and the electroconductive layer () after these layers have been formed by sputtering or vacuum deposition. Furthermore, an ITO layer () is formed on the entire glass surface including the intermediate layer () and the electroconductive layer () after the openings () are formed. In this configuration, the intermediate layer () comprises a mixture of at least one metal selected from chromium, molybdenum, and tungsten, and at least one oxide selected from oxides of silicon, oxides of aluminum, and oxides of titanium.
